I've had the Traveler for 4 mos. now and knock on wood, no problems so far. I'm going to buy a better compressor probably for Christmas, and was looking at doing it earlier, but decided to wait and see how the Traveler did over a longer period of time. I'm only filling my 4 guns, and have only done one complete fill from empty, as my Condor SS arrived with an empty tank. It runs quietly, hasn't gotten at all hot, and I clean the filter and filter cup out after every use. Have not run it on 12v at all yet, and probably won't any time soon.
What I do about the better/more expensive???? compressor depends entirely on what the Traveler does. So far so good! Now watch it die tomorrow...
